Often, frequency distributions are reported using unequal class widths because the frequencies of some groups otherwise be small or very large. Consider the following data, which represent the daytime household temperatt thermostat is set to when someone is home for a random sample of 739 households. Determine the class mid necessary, for each class and approximate the mean and standard deviation temperature.Click the icon to view the frequency distribution for the daytime household temperature.ClassClass Midpoint61-6465-6768-697071-72- 73-7677-80(Round to one decimal place as needed.)
